LAMP-SUPPORTING BRACKET.

SPECIFICATION forming part of Letters Patent No. 670,904, dated March. 26, 1901.

Application filed August 22, 1900. Serial No. 27,641. (No model.)

To ttZZ whom 211; may concern.-

Be it known that I, REINHART W. PITTMAN,

acitizen of the United States, residing in the city of New York, borough of Manhattan, in the county of New York and State of New York, have invented certain new and useful Improvementsin Lamp-Supporting Brackets, of which the following is a specification.

My invention relates to means for securing lamps in position on a desk or other support in such a manner that a wide range of adjustment is provided for and the lamp may be moved up or down, tilted, or adjusted horizontally, as required.

Primarily the object of the invention is the provision of a bracket of improved construction that will retain the lamp in its desired position, as will be hereinafter described.

In the accompanying drawings, Figure l is a perspective view of one form of my invention, showing it in place on a desk. Fig. 2 is a longitudinal vertical section of the form of the invention illustrated in Fig. 1. Fig. 3 is a section on line a; as, Fig. 2, looking in the direction of the arrow. Fig. 4 is a side elevation of the lamp-carrier to which the lamp is attached. Figs. 5 and 6 are side views of modifications hereinafter described.

Similar characters designate like parts throughout the several views.

Referring to the drawings, the numeral 10 designates a clamp, which serves as a supporting member, formed in two parts 12 and 13, the part 13 being provided with a vertical flange or projection 13 and'with a hook 13 and the part 12 with a similar flange or projection 12 and a pair of separated hooks 12 These vertical flanges 12 13', which extend from the adjacent ends of the plates at substantially right angles thereto, are perforated for the reception of a bolt or screw 14., on which a nut 14: is threaded for the purpose of tightening the plates 12 and 13 upon the desk.

Adjacent to its forward hooked end the plate 12 is provided with a vertical tubular boss or projection 15, perforated for the reception of a bolt 16, depending from a bracket 17, having perforated cars 17 through which a bolt 18 is passed, for a purpose hereinafter described.

Surrounding the bolt or stem 16 is a coiled spring 19, which bears at one end against the under side of the top plate of the vertical boss or projection and at its other end against a washer 20, supported by a nut 21, threaded upon the stem or bolt 16.

Swiveled upon the bolt 18 and between the cars 17 of bracket 17 is a lug 22', depending from a sleeve 22, through which a slotted tube 23 of a lamp-carrier (shown as a telescopic rod and designated in a general way by 24) is passed, and in this sleeve 23 is fitted the part 23' of said rod, having some frictional engagement with a tube 23 to retain it in position therein, which carries an eye 25, to which the clip for securing the lamp 26 is secured by a suitable bolt passing through said eye, thus permitting the lamp to be turned at an angle to the rod, if desired.

Attached to the sleeve 22 is a screw-eye 27, through which the flexible wires 28 for conveying the current to the lamp are passed, as shown in Figs. 1, 5, and 6, which may be turned down against the rod 23 to retain it in place in its longitudinal adjustment.

In the form of my invention illustrated in Fig. 5 a bracket 29 is illustrated having a bifurcated lug 30, adapted to he slipped over the edge of a support and to be retained in position by a bolt 31.

In Fig. 6 an angular bracket 32 is illustrated, by means of which the improvement may be secured by screws 33 to the side of a wall or other support.

In all the forms of my invention illustrated, however, the means for supporting the rod to which the lamp is attached are the same, and it will be seen that the joint formed between the bracket 17 and the lower side of the top of the boss or protuberance 15 of the plate 12 is while yielding yet sufficiently tight to retain the parts in any desired horizontal position when said bracket is swung on its bolt 16 as an axis and that the tension of the spring may be readily regulated by manipulating the nut 2i. In this way I am enabled to secure any desired adjustment of the lamp in a horizontal arc, and by pivoting the sleeve 22 be- -tween the lugs 17 (the grasping power of which may be readily regulated by the nut and bolt 18) the lamp may be adjusted to any desired position in a vertical arc and securely .20 said clamp; a member pivoted to said bracket;

a lamp-carrier mounted in said member; and a spring adapted to press the bracket and clamp together.

2. The combination, with a clamp adapted to engage a support, of a bracket swiveled on said clamp; a memberpivoted to said bracket; a lamp-carrier mounted in said member; and an adjustable spring adapted to press the bracket and clamp together. 3. The combination, with a plate and with means for securing said plate to a support, of

a bracket swiveled to the plate; a sleeve pivoted to the bracket; a rod adjustably mounted in the sleeve; and a lamp secured to the rod.

4. The combination, With a plate and with means for securing said plate to a support, of a bracket having a bolt passing through a chamber in the plate; a spring surrounding said bolt; a device for regulating the tension of said spring; a sleeve pivoted to the bracket; a rod adjustably mounted in the sleeve; and a lamp secured to the rod.

5. The combination, with two plates adapted to grasp a support, of means for drawing said plates together; a bracket swiveled to a boss formed on one of the plates; ears on said bracket; and alamp-supporting member having a lug pivoted between said ears.

6. The combination, with a plate having a tubular boss, of a bracket having a depending stem inserted through the top of the boss, and also having a pair of ears; a spring surrounding the stem; a nut for adjusting the tension of the spring; a sleeve pivoted between the ears of the bracket; a tube adjustable" in said sleeve; a rod telescoping the tube; and a'lamp adjustably mounted on the end of the rod.
